Krakatau volcano: eruption Oct 2018 - ash venting

Along with a small group, Tom Pfeiffer stayed on the island group during a Volcano Special tour from 13-19 Oct: the volcano's activity during this time fluctuated between phases of mild to strong ash venting along with occasional strombolian activity, as well as intermittent powerful vulcanian-type explosions. Ash emissions, both passive and accompanied by strombolian to vulcanian explosions were often continuous:
